Widely used as a pigment in paints, coatings, construction materials, plastics, rubber, and cosmetics due to its stable red color and resistance to UV light. Commonly employed in the production of rust-proof primers and anti-corrosion coatings for metal surfaces. Used in polishing compounds for glass, optics, jewelry, and metals because of its mild abrasive properties. Applied in the manufacturing of concrete tiles, bricks, and colored cements to provide reddish-brown hues. Utilized in thermite reactions for welding and cutting metals, where it acts as an oxidizer. Incorporated in some solid-state electronic devices, magnetic materials, ferrites, and sensors due to its semiconducting and weak ferromagnetic behavior. Used in water treatment processes to remove contaminants such as arsenic and phosphates. Also found in toners and ceramic products as a coloring agent.
